For a few months, RB28 was a new license-free radio with a large color screen. However, some customers were concerned that the screen could be scratched or damaged easily, so the simpler design of RB28B new license-free radio without the screen was released.
To compare with the two similar radios, we can also find some differences between RB28 and RB28B.

In drop tests, the RB28B is more resistant to drops because the screen is removed, so the whole body is made of durable material. If you need to bend over a lot or exercise vigorously, the RB28B will not be damaged if dropped. Just pick it up.
